The next PowerCore Combiners

PCC isn't really the most popular line. However it's bringing in some neat possibilities with each set that comes out. The Dinobots and Constructicons have been pretty great so far! But there will be more. Seeing as Hasbro is cycling through different group names for the 5-packs, what do you want next?

Personally, I want the Predacons and a Team Bullet Train. Maybe an Insecticon team would be neat too? Lets hear your thoughts.

Train bots would be cool, but with the size difference between the commander and the drones, I's rather have them being a freight train, with the drones being cargo cars (a tanker, a container carrier, a hopper, and some other, for example) and the commander a strong freight diesel engine. That would look much bulkier, and better proportioned.
